EDITOR's NOTE.
 
The New York Times has a web VN discussion forum attached to its collation of NYTimes articles on VN over the years. The Forum has been in operation since Feb. 1997 at the address below. The discussion section contains some 2800 postings and much of  it is of high quality. There seem to be a small number of contributors who often read the works simultaneously and carry on detailed and sometimes lengthy discussion about a particular work or theme.
I recommend browsing it.
